    Shawn Jackman (Jack) CWNE#54 is a personal friend and has been a mentor to me for many years.  I've had the pleasure and opportunity to work with Jack for 4 years. Jack is a great teacher who takes complex 802.11 standards and breaks them down so almost anyone can understand the concept at hand. I'm excited for you brother. Great job and job well done! Put another notch in the belt!

Onion Approach to wifi troubleshooting basics - Same, Better or Worse

I learned long ago working with end users is sometimes a blessing and a curse. Users have valuable information that will enable us as WiFi engineers to get a glimpse to the issues they are having. At times and from personal experience users may not always be truthful. I'm not saying their lying rather I'm point out the obvious.  Users I interview as part of my fact gathering phase sometimes don't have the time or don't clearly remember specific facts. In some cases I get that user who is the negative Nancy. You know her the gal who says nothing never works. It's always broken. It's always slow. 

When I make changes in an effort to resolve an issue I like to take the easy approach to get the users perspective if the issue has improved. Clearly some issues are black and white in terms that the issue is fixed and resolved or not.

Other times problems require small changes in an effort to improve a solution. Because maybe you aren't sure of the fix and you need to layer (Onion approach) back on complexity to see if we get improvement.
